In trying to reproduce the noicy behaviour with tificc, the output was fine. And after setting OMP_NUM_THREADS=1 the output became fine in the Oyranos example image viewer too while using pre and post CLUT curves.
So the noicy behaviour, while using cmsFLAGS_CLUT_POST_LINEARIZATION and cmsFLAGS_CLUT_PRE_LINEARIZATION, appears to be triggered by threading. kind regards Kai-Uwe Am 01.08.12, 11:55 +0200 schrieb Kai-Uwe Behrmann: > Find below a screenshot illustrating the issue: > http://www.oyranos.org/temp/lcms_post+pre_curves1.png > > Am 31.07.12, 14:40 +0200 schrieb Kai-Uwe Behrmann: >> While moving the image around inside the Oyranos example image viewer, I >> observed darker pixels obtaining some random noice.
